First of all, they are NOT KEYBOARDS. If you have seen them play live, which i have many times, you would have SEEN that all the "phaser" sounding solo's are Alexi. The side project is called WARMEN. On the track "The Evil That Warmen Do" on the cd UNKNOWN SOLDIER you can clearly hear that Sami Virtanen uses the same effects on the guitars that alexi uses. By the way, that cd sounds more like the COB Hate Crew messed around on Bodom's equipment between recording sessions.
Im just trying to figure out what type of pedal's he uses! If you don't know then don't bother replying!
